If your surge protector can't handle the load, you can plug the 16A cable directly into a 16A wall socket. This bypasses the surge protector but ensures safe operation.
I have Greensoul Jupiter Superb.
I would rate in 7/10. Comfort wise could be better but budget wise was a good option to consider for me.
Godrej and Greensoul chairs are the brands i've dealt with and would suggest them
If i had a choice i would not go with them. The only times i have dealt with them is when i have ordered from Ajio, and 90% of the times my experience have been bad.
Delayed deliveries, late return pickups, rude delivery boys etc etc
